A lip may extend downwardly relative to the lower surface of the tabletop, and the lip including an outer surface and an inner surface. A plurality of supports may be disposed in the inner surface of the lip, and a plurality of joints may be disposed in the inner surface of the lip. A joint may be disposed between adjacent supports. A distal portion of the lip may include a compression edge. A lower portion of the supports may contact the compression edge, and/or a lower portion of the joints may contact the compression edge.

BACKGROUND Field of the Invention

The present invention generally relates to structures including at leasta portion constructed from plastic and, more particularly, to furniture,such as tables, that may include molded plastic components.

Description of Related Art

Many different types of tables are known, and tables are used for avariety of purposes. For example, conventional tables may include legsthat are pivotally attached to a tabletop and the legs may be movablebetween a use position in which the legs extend outwardly from thetabletop and a storage position in which the legs are folded against thetabletop. Conventional tables with relatively large tabletops andfolding legs are often referred to as “banquet tables” and these tablesare frequently used in assembly halls, banquet halls, conventioncenters, hotels, schools, churches, and other locations where largegroups of people meet. These tables can often be positioned in anassortment of configurations and used in a variety of settings. When thebanquet tables are no longer needed, the table legs can be moved intothe storage position and the tables may be more easily moved or stored.

Conventional tables often include tabletops constructed from materialssuch as wood, particleboard, or metal. Tabletops constructed from wood,particleboard, or metal, however, are often relatively heavy and thismay make the table awkward or difficult to move. Tabletops constructedfrom wood or metal are also relatively expensive and these types oftabletops must generally be treated or finished before use. For example,tabletops constructed from wood must generally be sanded and painted,and metal tabletops must be formed into the desired shape and painted.In addition, because wooden and metal tabletops are relatively heavy,the cost of shipping and transportation of the tables may be increased.The weight of the tabletop may also make the tables more difficult tomove and store.

In order to decrease the weight of conventional tables, tabletops may beconstructed from relatively lightweight materials such as plastic.Tabletops constructed from lightweight materials, however, may requirelarge reinforcing members or other structural parts such as braces,brackets, supports, and the like to strengthen the tabletop. While theseadditional parts may increase the strength of the tabletop, the addedparts may also increase the weight of the table. These additional partsmay also result in increased manufacturing costs and require additionaltime to assemble the table. In addition, extra fasteners may be requiredto assemble and connect these parts to the table, which may requireextra time and labor during the manufacturing process. The additionalparts and fasteners may further increase the cost of the table and makethe table more difficult to manufacture.

Conventional tables may include a frame connected to the tabletop. Theframe may include a pair of side rails connected to sides of thetabletop using fasteners. Multiple fasteners may be required to securelyconnect the frame to the tabletop. When a large load or force is appliedto some known tables, the frame may bend or deform. In addition, a largeload or force may cause the fasteners used to connect the frame to thetabletop to detach or separate from the tabletop. The fasteners maydamage and/or tear through the tabletop if the load or force exceeds acertain amount.

The tabletops of some known tables may be damaged if a relatively largeload or force is applied. For example, a portion of the tabletop maybend or deform if a large load or force is applied to the tabletop. Forinstance, if a load or force is applied to an outer portion of thetabletop, the outer portion of the tabletop may bend or deform. Theouter portion of the tabletop may also be dented, pushed in, gouged, orbroken if an excessive force is applied.

BRIEF SUMMARY

A need therefore exists for a table that eliminates or diminishes theabove-described disadvantages and problems.

One aspect is a structure that may be at least partially constructedfrom plastic. For example, the structure may be at least partiallyconstructed from molded plastic. If desired, all or a portion of thestructure may be constructed from blow-molded plastic.

Another aspect is a structure that may include a generally planarportion. For example, the structure may be a tabletop and the tabletopmay include a generally planar portion. For instance, the tabletop mayhave a generally planar upper portion or surface, and/or a generallyplanar lower portion or surface. The tabletop may also includeprojecting or protruding structures, such as a lip. The lip may extenddownwardly relative to the lower portion of the tabletop, and the lipmay be disposed about an exterior of the tabletop. The lip may extendabout all or a portion of the tabletop, and the lip may form at least aportion of a sidewall or outer edge of the tabletop. The lip may also bespaced inwardly from the outer portion of the tabletop. The lip may havea generally constant height, but the height of the lip may vary. The lipand the tabletop may be integrally formed during a molding process aspart of a unitary, one-piece construction. For convenience andreadability, the structure disclosed in this application will begenerally described in connection with an exemplary tabletop. One ofskilled in the art will appreciate, after reviewing this disclosure,that the structure could be other suitable articles, constructions,devices, and the like. For example, the structure could be articles offurniture, sporting goods, sheds, storage containers, etc. The structurecould also be various parts and pieces, such as furniture components andthe like.

Still another aspect is a tabletop may a lip, and the lip may include anouter wall and an inner wall. The outer wall of the lip may form atleast a portion of an outer edge of the tabletop. The outer wall and theinner wall may be disposed in a generally parallel configuration, and aportion of the outer wall and the inner wall may be separated by adistance. A portion of the outer wall and the inner wall may also touchor contact. In an exemplary embodiment, the distal portion of the outerwall and the inner wall (e.g., the lower portion of the lip) may touchor contact, and the distal portion of the lip may have a compressionedge. The compression edge may be relatively high-strength, and durable.The compression edge may have increased structural integrity because itmay have a double wall thickness. The compression edge may have a heightgenerally equal to about fifty percent (50%) of a height of the lip. Thecompression edge may also be larger or smaller. For example, thecompression edge may be greater than about fifty percent (50%) of theheight of the lip, such as about sixty percent (60%), about seventypercent (70%), about eighty percent (80%), about ninety percent (90%),or more. The compression edge may have a height less than about fifty(50%) of the height of the lip, such as about forty percent (40%), aboutthirty percent (30%), about twenty percent (20%), about ten percent(10%), or less. The compression edge may have a generally uniformheight, and the compression edge may extend about all or at least aportion of the tabletop. The compression edge may have a generallyuniform area of contact between the inner wall and the outer wall of thelip. Advantageously, if the compression edge has a generally uniformsize, shape, configuration, and/or arrangement, the compression edge mayhave generally uniform properties and characteristics. This may allow atleast a portion of the tabletop, such as the outer perimeter and/orlower portion of the lip, to have generally uniform properties andcharacteristics.

Yet another aspect is a tabletop that may include one or more supports,and the supports may be disposed in the inner wall of the lip. Thesupports may be formed by a portion of the inner wall of the lip, andthe supports may extend inwardly towards a center portion of thetabletop. The supports may include an upper portion connected to thelower surface of the tabletop, and the supports may include a lowerportion disposed towards a distal end of the lip. The supports may havea height that may be measured from the lower surface of the tabletop tothe lower portion of the support, and the supports may have a generallyconstant height. The height of the supports may be generally equal toabout fifty percent (50%) of a height of the lip. The supports may alsobe larger or smaller. For example, the supports may have a heightgreater than about fifty percent (50%) of the height of the lip, such asabout sixty percent (60%), about seventy percent (70%), about eightypercent (80%), about ninety percent (90%), or more. The supports mayhave a height less than about fifty (50%) of the height of the lip, suchas about forty percent (40%), about thirty percent (30%), about twentypercent (20%), about ten percent (10%), or less. The supports may havegenerally uniform construction, such as a generally uniform height,width, and/or thickness. Additionally, the supports may have a generallyconsistent size, shape, configuration, and/or arrangement. In anexemplary embodiment, one or more of the supports may be disposed in apattern, and the pattern may include a plurality of supports disposed inan order, grouping, and/or array. The pattern may extend about all or atleast a portion of the tabletop. For example, a first portion of thetabletop, such as a first side, may include a first plurality ofsupports disposed in a pattern. A second portion of the tabletop, suchas a second side, may include a second plurality of supports disposed ina pattern. In an exemplary embodiment, the pattern on the first side ofthe tabletop may be symmetrical, the same, or a mirror image of thepattern on the second side of the tabletop. The pattern may include oneor more supports disposed in a generally consistent arrangement orlayout. The pattern may also include one or more supports disposed in aregular or repeating order, and one or more of the supports may bedisposed in a balanced or even formation. The supports may havegenerally uniform properties and characteristics because the supportsmay have generally uniform shapes, sizes, configurations, and/orarrangements. The tabletop may have generally uniform properties orcharacteristics because the supports may have generally uniform shapes,sizes, configurations, and/or arrangements, and the supports may bedisposed in a generally uniform and constant pattern.

Still yet another aspect is a tabletop that may include one or moreattachment portions, and the attachment portions may be sized andconfigured to facilitate attachment of the frame to the tabletop. Theattachment portions may be formed by and/or disposed in the inner wallof the lip, and the attachment portions may have generally the sameheight and width. In an exemplary embodiment, the attachment portionsmay have generally the same height as the supports. The width of theattachment portions, however, may be larger or smaller than the width ofthe supports. For example, the attachment portions may have a width thatis about twice as large as a width of the supports. The attachmentportions may also have a larger width, such as about three times, aboutfour times, about five times, or more that the width of the supports.The attachment portions may also have a smaller width, such as aboutone-half the width of the supports.

The attachment portions may facilitate attachment of a frame to thetabletop. For instance, if the frame is attached to the tabletop by oneor more fasteners, such as screws, the attachment portions may be sizedand configured to receive a portion of the fastener. The attachmentportions may have generally uniform sizes, shapes, configurations,and/or arrangements, which may create attachment portions with generallyuniform properties and characteristics. The generally uniform size,shape, configuration, and/or arrangement of the attachment portions mayallow at least a portion of the tabletop, such as the outer perimeter orlip, to have generally uniform properties and characteristics.

A further aspect is a tabletop that may include one or more joints,couplings, or connections disposed in and/or formed by the inner wall ofthe lip. The joints may include a portion of the inner wall of the lipdisposed at least proximate a portion of the outer wall of the lip. Inan exemplary embodiment, a portion of the inner wall may contact ortouch the outer wall of the lip to form the joint. The joint may extendfrom the lower portion of the tabletop to the distal portion of the lipand, as discussed above, the distal portion of the lip may be acompression edge. The joints may be disposed in a generally parallelconfiguration, and the joints may be spaced apart by a generallyconstant distance. The joints may have a generally uniform height,width, and/or area of contact between the inner wall and the outer wallof the lip. Advantageously, if the joints have a generally uniform size,shape, configuration, and/or arrangement, the joints may have generallyuniform properties and characteristics. This may allow at least aportion of the tabletop, such as the lip, to have generally uniformproperties and characteristics.

In an exemplary embodiment, a joint may be disposed on each side of asupport. If a plurality of supports is aligned, a joint may be disposedbetween adjacent supports. The joints and the supports may havegenerally the same height, and the joints and the supports may bedisposed in a generally uniform pattern. If the joints and supports aredisposed in a pattern with generally consistent sizes, shapes,configurations, and/or arrangements, at least a portion of the tabletopmay have generally uniform properties and characteristics.

Another further aspect is a tabletop that may include a pattern ofsupports, joints, and/or attachment portions. For example, the patternmay include a series of generally aligned supports. The pattern may alsoinclude a joint disposed between each of the adjacent supports and/or ajoint disposed on each side of the supports. In addition, the patternmay include one or more attachment portions. For instance, a number ofsupports and joints may be disposed in a row or line, and one or moreattachment portions may be disposed in the row or line. The pattern maybe symmetrically disposed on one or more of the sides and/or ends of thetabletop. The pattern may include an attachment portion disposed towardsor proximate an end of the tabletop and one or more supports may bedisposed on one or both sides of the attachment portion. The attachmentportion and the supports may be separated by a generally equal distance,and the attachment portion and the supports may be separated by a joint.Depending upon the size of the tabletop, for example, additionalattachment portions may be disposed towards a middle portion of thetabletop.

Advantageously, one or more of the supports, joints, and/or attachmentportions in the pattern may have generally the same size, shape,configuration, and/or arrangement. For example, the supports, joints,and/or attachment portions may have generally the same height, and thesupport and the attachment portions may extend inwardly generally thesame amount and/or have generally the same thickness. Because thesupports, joints, and/or attachment portions may have generally the sameheight and may be disposed in a generally uniform pattern, the tabletopmay have generally uniform properties and characteristics.

A still further aspect is a tabletop that may be a unitary, one-piecestructure. For example, the tabletop may include one or more supports,joints, and/or attachment portions, and each of these components may beintegrally formed with the tabletop as part of a unitary, one-piecestructure.

Yet another further aspect is the tabletop may include a volume orhollow interior portion. The hollow interior portion may be at leastpartially disposed between an upper surface and a lower surface of thetabletop. The supports may be connected to the lower surface of thetabletop, and the supports may include a volume or a hollower interiorportion. The hollow interior portion of the tabletop may be connected toand/or in fluid communication with the hollow interior portion of thesupports.

Still yet another further aspect is the tabletop may include one or moreattachment portions, and the attachment portions may include a volume orhollow interior portion. The upper portion of the attachment portionsmay be connected to the lower surface of the tabletop. The hollowinterior portion of the tabletop may be connected to and/or in fluidcommunication with the hollow interior portion of the attachmentportions.

A still further aspect is a tabletop may include one or more joints andthe joints may at least partially, at least substantially, and/orentirely prevent direct fluid communication between adjacent structures,such as between adjacent supports. One or more of joints may at leastpartially, at least substantially, and/or entirely prevent direct fluidcommunication between the attachment portion and adjacent structures,such as between the attachment portion and adjacent supports.

A further aspect is a tabletop that may include generally uniformproperties and characteristics. For example, one or more of thesupports, joints, and/or attachment portions may include an end, such asa proximal end, and the end may be disposed proximate or connected to alower surface of the tabletop. In addition, the supports, joints, and/orattachment portions may have a height that is generally the same. Thesupports and attachment portions may also have a thickness that isgenerally the same. The supports, joints, and/or attachment portions mayhave a distal end, and the distal end may be disposed at least proximateand/or connected to the distal portion of the lip, which may be acompression edge. The supports, joints, attachment portions, and/orcompression edge may have generally consistent sizes, shapes,configurations, and/or arrangements, which may allow at least a portionof the tabletop, such as the outer perimeter or lip, to have generallyuniform properties and characteristics.

Another aspect is a tabletop that may include a pattern, and at least aportion of the pattern may be disposed in a generally uniform or regulararrangement. For example, the pattern may include one or more supports,joints, attachment portions, and/or compression edges. The pattern mayrepeat along one or more sections of the tabletop, such as along innersurface of the lip. In an exemplary embodiment, the pattern may bedisposed along at least a portion of one or more sides and/or ends ofthe tabletop. For example, the pattern may have a length generally equalto or less than a length of a siderail of the frame. The pattern mayalso extend about at least a portion of the perimeter, such more thanabout fifty percent (50%) of the perimeter, more than about sixtypercent (60%) of the perimeter, more than about seventy percent (70%) ofthe perimeter, more than about eighty percent (80%) of the perimeter,more than about ninety percent (90%) of the perimeter, or more. Thepattern may be disposed in one or more corners of the tabletop, or adifferent pattern may be disposed in one or more corners or differentsections of the tabletop. The corners, ends, or other portions of thetabletop, however, may not include the pattern. In addition, portions ofthe tabletop, such as the ends and/or corners, may not include supports,joints, attachment portions, and/or compression edge. After reviewingthis disclosure, one skilled in the art will appreciate that thetabletop may include any suitable number of supports, joints, attachmentportions, and/or compression edges, and none of these structures may berequired. For example, the attachment portions may not be required ifthe table does not include a frame or if the frame is attached to otherportions of the tabletop. In addition, one skilled in the art willappreciate after reviewing this disclosure that the tabletop may includeother components, features, aspects, and the like.

Another aspect is the molded plastic structure may be constructed fromblow-molded plastic and the lip may be integrally formed during theblow-molding process as part of a unitary, one-piece construction. Forexample, during the blow-molding process, gas may flow through thehollow interior portions of the tabletop, supports, and/or attachmentportions. In an exemplary embodiment, the gas may have sufficientpressure to form the lip, supports, joints, attachment portions, and/orcompression edge during the blow-molding process.

Advantageously, the supports, joints, attachment portions, and/orcompression edge may help create a lip that is high-strength, impactresistant, and aesthetically pleasing. The supports, joints, attachmentportions, and/or compression edge may also help create a tabletop withgenerally uniform properties and characteristics. In addition, arelatively small number of attachment portions may be required. Forexample, a tabletop with a length of about seventy-two (72) inches mayinclude two, three, four, or more attachment portions along the length.It will be appreciated, after reviewing this disclosure, that the tablemay include any suitable number, size, shape, configuration, and/orarrangement of supports, joints, attachment portions, and/or compressionedges depending, for example, upon the intended use of the table.

A detaileddescription of some exemplary embodiments now follows.

As shown in FIGS. 1A and 1B, an exemplary table 10 may include atabletop 12 and the tabletop 12 may be constructed from molded plastic.The tabletop 12 may include an upper portion 14, such as an uppersurface, and a lower portion 16, such as an underneath or lower surface.The upper portion 14 may be spaced apart from the lower portion 16 ofthe tabletop 12 by a distance, which may be a generally constantdistance in some embodiments. The tabletop 12 may also include a hollowinterior portion 18, such as a volume, disposed between the upperportion 14 and the lower portion 16 of the tabletop 12.

The tabletop 12 may include one or more sides and/or ends, such as afirst side 20, a second side 22, a first end 24, and a second end 26.The tabletop 12 may include one or more corners 28. The tabletop 12 mayinclude a lip 30, and the lip 30 may be disposed at least proximate anouter perimeter 32 of the tabletop 12. The lip 30 may also be spacedinwardly from the perimeter 32, and the lip 30 may have differentheights, sizes, shapes, configurations, and/or arrangements. Forexample, the lip 30 may be disposed along the sides 20, 22, ends 24, 26,and/or corners 28 of the tabletop 12. If the tabletop 12 is constructedfrom a moldable material such as plastic, the tabletop 12, the upperportion 14, the lower portion 16, the hollow interior portion 18, thesides 20, 22, the ends 24, 26, the corners 28, and/or the lip 30 may beintegrally formed as part of unitary, one-piece structure during themolding process. If the tabletop 12 is constructed from plastic, and thetabletop 12 may be formed by blow-molding, injection molding, rotarymolding, and the like. The molded plastic tabletop 12 may be constructedfrom materials such as high-density polyethylene (HDPE) or anothersuitable polymers or plastics. The tabletop 12 may also be constructedusing various materials such as wood, metal, non-plastic materials,plant based materials, and the like. The tabletop 12 may be constructedusing other processes and methods depending, for example upon thematerial used to construct the tabletop 12.

The tabletop 12 may include a center portion or body 34, and at least aportion of the center portion 34 may have a generally planarconfiguration. For example, the center portion 34 may include agenerally planar upper portion or surface 14 and/or a generally planarlower portion or surface 16. The lip 30 may extend downwardly and/oroutwardly relative to the upper portion 14, the lower portion 16, and/orthe center portion 34 of the tabletop 12. As shown in the accompanyingfigures, the lip 30 may extend around an entirety of the perimeter 32 ofthe tabletop 12. In other exemplary embodiments, the lip 30 may extendalong one or more portions of the tabletop 12, and the lip 30 mayinclude one or more sections.

The table 10 may include a one or more support structures 36, and thesupport structures 36 may be sized and configured to support thetabletop 12 above a surface such as the floor or ground. The supportstructures 36 may include one or more legs 38, and the supportstructures 36 may be movable between an extended or use position and acollapsed or storage position relative to the tabletop 12. As shown inthe accompanying figures, the support structures 36 may include a pairof legs 38, and the support structures 36 may be height adjustable. Thesupport structures 36 and/or legs 38 may have different shapes, sizes,configurations, and/or arrangements depending, for instance, upon theintended use of the table 10. For example, the table 10 may includesupport structures, legs, or other aspects or features such as shown inU.S. Pat. No. 10,470,561 and U.S. Patent Publication Nos. 20190150608and 20200077785, each of which is incorporated by reference in itsentirety.

The table 10 may include a frame 40 that is connected to the tabletop12, and the frame 40 may include one or more rails, such as a firstsiderail 42 and a second siderail 44. The first siderail 42 may bedisposed at least proximate the first side 20 of the tabletop 12, andthe second siderail 44 may be disposed at least proximate the secondside 22 of the tabletop 12. The first and second siderails 42, 44 mayextend along a length of the tabletop 12, and the siderails 42, 44 mayhelp support the tabletop 12. If the table 10 is a fold-in-half table,then a first portion of the first side rail 42 may be connected to afirst portion of the tabletop 12 and a second portion of the first siderail 42 may be connected to a second portion of the tabletop 12.Similarly, a first portion of the second side rail 44 may be connectedto a first portion of the tabletop 12 and a second portion of the secondside 44 rail may be connected to a second portion of the tabletop 12.The first and second portions of the first side rail 42 may be connectedby a hinge, and the first and second portions of the second side rail 44may be connected by a hinge. Exemplary fold-in-half table are shown inU.S. Pat. Nos. 7,278,361 and 8,555,791, each of which is incorporated byreference in its entirety.

The support structures 36 may be connected to the frame 40. Forinstance, the support structures 36 may be rotatably connected to thefirst and second siderails 42, 44 of the frame 40. The supportstructures 36, however, do not have to be connected to the first andsecond siderails 42, 44 and/or the frame 40. Instead, the supportstructures 36 may be connected to any suitable portions of the tabletop12 and/or table 10. It will also be appreciated that the table 10 mayinclude any suitable number and type of support structures 36 and/orlegs 38 depending, for example, upon the intended use of the table 10.In addition, it will be appreciated that the frame 40, the firstsiderail 42, and/or the second siderail 44 may have various sizes,shapes, configurations, and arrangements. It will further be appreciatedthat the support structures 36, the legs 38, the frame 40, the siderails 42, 44, and other components, aspects, and features are notrequired; and the table 10 may have other components, aspects, andfeatures.

The support structures 36 may be connected to other portions of thetabletop 12 and/or frame 40. For instance, one or more braces 46 may beconnected to the support structures 36, and the braces 46 may beconnected to other portions of the table 10 and/or frame 40, such as acenter crossbar 48.

The table 10 may be sized and configured to be stacked with one or moreadditional tables. In the stacked configuration, the tables 10 may benested together to reduce a height of the stacked tables 10. Reductionin the height may allow the tables 10 to be shipped, stored, andtransported in a smaller volume. This may result in significant costsavings because, for example, less storage space may be required and asubstantial reduction in transportation costs may be achieved. The table10 may be stackable and/or may include one or more features, aspects,components, and the like as shown and described in U.S. Pat. Nos.8,347,795; 8,397,652; 8,408,146; 8,622,007; and 9,138,050; each of whichis incorporated by reference in its entirety.

As shown in FIG. 1B, the siderails 42, 44 of the frame 40 may bedisposed at least proximate the lip 30 and/or the perimeter 32 of thetabletop 12. For example, the first side rail 42 may be disposed alongthe first side 20 of the tabletop 12, and the second side rail 44 may bedisposed along the second side 22 of the tabletop 12. Advantageously, ifthe side rails 42, 44 are disposed proximate the sides 20, 22 of thetabletop 12, then the sides of the tabletop 12 may be supported by theframe 40, which may help create a strong and sturdy table 10. Inaddition, the siderails 42, 44 may be sized and configured to directlysupport one or more portions of the lip 30. For example, a first portionof the siderails 42, 44 may support a first portion of the lip 30, and asecond portion of the siderails 42, 44 may support a second portion ofthe lip 30. Because the lip 30 may be supported by the siderails 42, 44in more than one position, the lip 30 may be strong, sturdy, and held ina generally fixed position. In addition, the lip 30 may be supportedsuch that the lip 30 does not undesirably bend or flex. The lip 30 mayalso be less likely to be damaged, dented, or deformed because the lip30 may be supported in multiple locations by the siderails 42, 44 of theframe 40.

The frame 40 may also help prevent the tabletop 12 from being damagedwhen a large load or force is applied to the table 12. For instance, ifthe table 10 is dropped or knocked over, the support of the lip 30 bythe frame 40 may help prevent damage to the tabletop 12. In addition,the frame 40 may allow the tabletop 12 to receive and/or support largeloads or forces without the tabletop 12 being dented, crushed, deformed,or otherwise damaged. Further, because the frame 40 may directly supportthe lip 30, that may facilitate stacking of the tables 10 becauseadditional tables 10 may be disposed in the stacked configuration, andthe tables 10 may be less likely to be damaged by sudden impacts.

In an exemplary embodiment, a first portion of the lip 30, such as theportion of the lip 30 proximate the tabletop 12, such as the uppersurface 14 and/or the lower surface 16 of the tabletop 12, may bereferred to as an upper or proximal portion 50 of the lip 30. Thesiderails 42, 44 of the frame 40 may directly support the proximalportion 50 of the lip 30. A second portion of the lip 30, such as thelower portion of the lip 30, may be referred to as the lower or distalportion 52 of the lip 30. The distal portion 52 of the lip 30 may bedirectly supported by the siderails 42, 44 of the frame 40.

The lip 30 may include an inner wall 54 and an outer wall 56, and thelip 30 may have a thickness that may be measured between the inner andouter walls 54, 56. The proximal and distal portions 50, 52 of the lip30 may have similar or different thicknesses. For example, the proximalportion 50 of the lip 30 may have a larger thickness than the distalportion 52 of the lip 30. The proximal portion 50 of the lip 30 may alsohave a smaller thickness than the distal portion 52 of the lip 30, orthe proximal and distal portions 50, 52 of the lip 30 may have the samethickness.

As shown in FIG. 1B, the tabletop 12 may include one or more depressions60, which may also be referred to as tack-offs. The depressions 60 maybe sized, shaped, configured, and/or arranged to provide increasedstrength, stiffness, and/or rigidity to the tabletop 12. The depressions60 may cover a majority, substantially all, or the entirety of the lowerportion 16 of the tabletop 12. In addition, the depressions 60 may havea generally uniform shape, size, configuration, and/or arrangement. Thedepressions 60 may have an elongated shape, which may be aligned with anaxis, and the depressions 60 may be disposed in one or more rows and/orcolumns. For example, the depressions 60 may be aligned in rows thatextend along a length of the tabletop 12, and the depressions 60 may bedisposed in columns that extend along a width of the tabletop 12. Thedepressions 60 in adjacent rows and/or columns may be offset, and thedistance between adjacent depressions in the rows and/or columns may begenerally the same. In an exemplary embodiment, the distance betweenadjacent depressions in the rows and/or columns may be generallyconstant or equidistant. The distance between adjacent rows and/orcolumns may also be generally constant or equidistant.

The depressions 60 may be used to create a tabletop 12 with generallyuniform characteristics or qualities. For example, if the depressions 60are generally consistently spaced, that may allow the upper portion 14of the tabletop 12 to be uniformly supported. In addition, if thedepressions 60 are separated by a generally constant distance, which maybe measured from a center of one depression 60 to a center of anadjacent depression 60, that may create a tabletop 12 with generallyuniform characteristics or qualities. The distance between adjacentdepressions 60 may be measured longitudinally, laterally, or at an angledepending, for example, upon the arrangement of the depressions 60.

The depressions 60 may also be disposed in a pattern and the depressionsmay be generally aligned and/or disposed in predetermined locationswithin the pattern. The pattern may include, for example, a number ofrows and/or columns of the depressions 60. The depressions 60 may alsobe disposed in other suitable forms and patterns, and the depressions 60may have other shapes, sizes, configurations, and/or arrangements,depending, for example, upon the intended use of the tabletop 12.

The depressions 60 may have different characteristics depending, forexample, upon the particular configuration of the depressions. Forexample, the depressions 60 may have a non-circular configuration, whichmay provide increased strength in one direction in comparison to anotherdirection. Advantageously, if the depressions 60 have differentcharacteristics, then the depressions can be arranged or configured sothe structure has certain characteristics. In particular, thedepressions 60 may be arranged into a pattern to maximize certaincharacteristics and/or create a structure with generally uniformcharacteristics. For instance, the pattern may include generallyuniformly spaced depressions 60 that are separated by a generallyconstant distance and/or disposed in standardized arrangement. Aconsistent arrangement of the depressions 60 may help create a structurewith uniform characteristics, such as generally uniform strength andstructural integrity.

As shown in FIGS. 2A-2C, the support structures 36 may be connected tothe frame 40 by one or more cross members 62. The cross members 62 maybe part of the support structures 36, part of the frame 40, orindependent components. The legs 38 may be securely or rotatablyconnected to the cross members 62, and the cross members 62 may besecurely or rotatably connected to the frame 40. For example, as shownin FIG. 2C, an end of the cross member 62 may include a tapered section64, and the tapered section 64 may be connected to the siderails 42, 44of the frame 40. For instance, the siderails 42, 44 of the frame 40 mayinclude a first side 66, which may be an inner surface or inner portionthat is generally disposed towards the center portion 34 of the tabletop12. The first side 66 of the siderail 42, 44 may have a generally planarconfiguration, and the first side 66 may include an opening or aperture68 that facilitates connection of the cross member 62 to the frame 40.The siderails 42, 44 may include a second side 70, which may be an outersurface or outer portion that is generally disposed away from the centerportion 34 and/or towards the lip 30. In an exemplary embodiment, thesecond side 70 may include multiple different segments, such as a firstsegment 72, a second segment 74, and a third segment 76. The firstsegment 72 may be disposed towards the upper portion 14 and/or lowerportion 16 of the tabletop 12, and the third segment 76 may be disposedtowards the lower or distal portion 52 of the lip 30. As shown in theaccompanying figures, the first segment 72 and the third segment 76 maybe disposed in generally parallel planes, and the second segment 74 maybe disposed at an angle relative to the first segment 72 and/or thethird segment 76. One or more of the segments 70, 72, 74 may include anopening or aperture 78 that facilitates connection of the cross member62 to the frame 40. For example, the opening or aperture 78 may bedisposed in a portion of the first segment 72 and the second segment 74,and the tapered section 64 of the cross member 62 may at least partiallyextend through the opening in the first and second segments 72, 74.

The siderails 42, 44 may include a first portion 80, such as an upperportion or surface, and the first portion 80 may be disposed at leastproximate the lower portion 16 of the tabletop 12. In addition, thefirst portion 80 may be sized and configured to support the tabletop 12.The first portion 80 may be disposed in a receiving portion 84 in thelower portion 16 of the tabletop 12. The first portion 80 may bedisposed at least proximate a connection or intersection of the lowerportion 16 of the tabletop 12 and the lip 30. The siderails 42, 44 mayinclude a second portion 82, such as lower portion or surface, and thelower portion 82 may be disposed at least proximate the distal portion52 of the lip 30.

The first and second sides 66, 70 of the siderails 42, 44 may beseparated by different distances. For example, the upper portion 80 ofthe siderails 42, 44 may have a smaller width than the lower portion 82of the siderails 42, 44. For example, the width of the upper portion 80of the siderails 42, 44 may be generally equal to or less than aboutninety percent (90%) of the width of the lower portion 80, generallyequal to or less than about eighty percent (80%) of the width of thelower portion 80, generally equal to or less than about seventy percent(70%) of the width of the lower portion 80, generally equal to or lessthan about sixty percent (60%) of the width of the lower portion 80,generally equal to or less than about fifty percent (50%) of the widthof the lower portion 80, generally equal to or less than about fortypercent (40%) of the width of the lower portion 80, generally equal toor less than about thirty percent (30%) of the width of the lowerportion 80, generally equal to or less than about twenty percent (20%)of the width of the lower portion 80, generally equal to or less thanabout ten percent (10%) of the width of the lower portion 80, or less.

The siderails 42, 44 may be sized and configured to contact and/orsupport multiple portions of the tabletop 12. For example, the upperportion 80 of the siderails 42, 44 may be sized and configured tocontact and/or support the lower portion 16 of the tabletop 12. One ormore of the segments 72, 74, 76 of the siderails 42, 44 may be sized andconfigured to contact and/or support one or more portions of the innerportion 54 of the lip 30. For example, the first segment 72 of the siderails 42, 44 may be sized and configured to contact and/or support theproximal portion 50 of the lip 30, and the third segment 76 may be sizedand configured to contact and/or support the distal portion 52 of thelip 30. Advantageously, because different portions of the lip 30 may besupported by different portions of the siderails 42, 44, the lip 30 maybe securely supported and may not undesirably flex or bend. Afterreviewing this disclosure, one skilled in the art will appreciate thatthe lip 30 and the frame 40 may have other suitable shapes, sizes,configurations, and/or arrangements depending, for example, upon theintended use of table 10.

As shown in FIGS. 3A and 3B, the siderail 42, 44 may have an elongatedconfiguration, and the siderail 42, 44 may have a length that isgenerally equal to or less than a length of the tabletop 12. Thesiderail 42, 44 may include the openings 68, 78 that facilitateconnection of the support structures 36 to the frame 40. As discussedabove, the openings 68, 78 may be sized and configured to receive thetapered section 64 of the crossmember 62. The siderail 42, 44 may alsoinclude a bracket 86, and the bracket 86 may be disposed proximate acenter or midpoint of the siderail 42, 44. The bracket 86 may facilitateconnection of the center crossbar 48 to the frame 40. For example, thebracket 86 may include an opening or aperture 90, and an end of thecenter crossbar 48 may be disposed in the opening 90. In addition, thesiderails 42, 44 may include one or more openings or apertures 92, andthe openings 92 may be sized and configured to facilitate attachment ofthe siderails 42, 44 to the tabletop 12. For instance, the openings 92may be sized and configured to allow a connector 94, such as a screw orfastener, to be inserted and the connector 94 may attach the siderail42, 44 to the tabletop 12. After reviewing this disclosure, one skilledin the art will appreciate that the tabletop 12, the support structures36, and the frame 40 may have various shapes, sizes, configurations,and/or arrangements, and these components may be connected using otherstructures, systems, and/or methods. It will also be appreciated thatthese components may be directly or indirectly connected.

As shown in FIGS. 4A and 4B, the lip 30 may be disposed about all or aportion of the perimeter 32 of the tabletop 12. The lip 30 may includeone or more supports 100, and the supports 100 may be disposed in and/orformed by the inner wall 54 of the lip 30. The supports 100 may extendinwardly towards the central portion 34 of the tabletop 12. The supports100 may also be connected to the lower portion 16 of the tabletop 12. Inan exemplary embodiment, the supports 100 may be disposed at leastproximate the intersection of the inner wall 54 of the lip 30 and thelower portion 16 of the tabletop 12. The supports 100 may be sized andconfigured to provide additional support to one or more portions of thetabletop 12 and/or the lip 30.

Advantageously, the supports 100 may increase the strength, rigidity,structural integrity, and/or impact resistance of the lip 30. Thesupports 100 may also reduce the likelihood that the tabletop 12 isdamaged during use, shipping, and/or storage. For instance, the table 10may be constructed and then shipped to a retailer or end user. Duringshipping, storage, and/or display of the table 10, the table 10 may bedropped, fall off a shelf, or otherwise be subject to large impacts.Items may also fall or crash into the table 10 during shipping, storage,and/or display. In addition, the table 10 may be subject to considerablemovement, vibrations, forces, and the like while being shipped, stored,and/or displayed. These impacts and forces may damage one or moreportions of the table 10, such as the edges of the tabletop 12. Thesupports 100 be sized and configured to strengthen one or more portionsof the tabletop 12, such as the lip 30, which may help prevent damage tothe tabletop 12.

The supports 100 may also help reduce or prevent damage during use. Forexample, the table 10 may be configurable in use and storagearrangements, and the table 10 may be stored between uses. The table 10may be dropped, tipped on its side, stuffed into a storage closet, etc.,which may result in contact between the tabletop 12 and various items(e.g., the floor, closet doors, other tables, etc.). The supports 100may reduce or prevent damage to the tabletop 12.

In an exemplary embodiment, the supports 100 may be formed by the innerwall 54 of the lip 30. The supports 100 may protrude inwardly towardsthe center portion 34 of the tabletop 12.

The supports 100may include a lower or distal portion 104, and the lower portion 104 maybe disposed towards the distal portion 52 of the lip 30. The supports100 may include a contact surface 106, and the contact surface 106 maybe sized and configured to contact a portion of the frame 40, such asthe first segment 72 of the siderail 42, 44. The lower portion 104 ofthe support 100 may be sized and configured to be disposed at leastproximate the second segment 74 of the siderail 42, 44. The lowerportion 104 and the contact surface 106 may be sized and configured tocontact, support, and/or be disposed at least proximate the second side70 of the side rail 42, 44.

The supports 100 may include one or more sides, such as a first side 108and a second side 110. The support 100 may also include one or morerounded or curved portions, such as rounded corners. The support 100 mayfurther include a volume or hollow interior portion 112, and the hollowinterior portion 112 of the support 100 may be in fluid communicationwith the hollow interior portion 18 of the tabletop 12.

As shown in the accompanying figures, the tabletop 12 may include aplurality of supports 100, and the supports 100 may be generallyaligned. For example, a plurality of supports 100 may be generallyaligned in a straight line along the inner surface 54 of the lip 30. Thesupports 100 may extend along at least a majority of the inner surface54 of the lip 30, and the supports 100 may be disposed at leastproximate the siderail 42, 44 when the frame 40 is connected to thetabletop 12. The supports 100 may be enclosed or at least partiallybounded by the lip 30 and the siderails 42, 44 when the frame 40 isattached to the tabletop 12.

One or more of the supports 100 may be disposed in a pattern, and thetabletop 12 may include one or more patterns. An exemplary pattern mayinclude a plurality of the supports 100, and the supports 100 may bedisposed in a generally consistent configuration and/or arrangement. Inaddition, one or more of the supports 100 in the pattern may havegenerally the same size, shape, configuration, and/or arrangement. Thegenerally consistent configuration and/or arrangement of the supports100 may support at least a portion of the lip 30 in a generally uniformmanner. In an exemplary embodiment, the lip 30 may have generallyconsistent properties and/or characteristic, such as strength,structural integrity, rigidity, and the like, because, among otherreasons, the lip 30 may be supported by a plurality of generally similarsupports 100 that are disposed in a generally uniform pattern.

One or more of the supports 100 may be disposed in a regular, repeatingpattern. For example, the supports 100 may be generally aligned in aparallel configuration along a length of the inner wall 54 of the lip30. The supports 100 may also be disposed in a generally consistentmatter along a length of the inner wall 54 of the lip 30. In anexemplary embodiment, the supports 100 may be disposed along more thanabout fifty percent (50%) of the inner wall 54 along the sides 20, 22 ofthe tabletop 12, more than about sixty percent (60%) of the inner wall54 along the sides 20, 22 of the tabletop 12, more than about seventypercent (70%) of the inner wall 54 along the sides 20, 22 of thetabletop 12, more than about eighty percent (80%) of the inner wall 54along the sides 20, 22 of the tabletop 12, more than about ninetypercent (90%) of the inner wall 54 along the sides 20, 22 of thetabletop 12, or more.

Forexample, the siderails 42, 44 of the frame 40 may be disposed at leastproximate the sides 20, 22 of the tabletop 12, and the pattern may bedisposed along one or more sections of the lip 12 where the siderails42, 44 are attached. In an exemplary embodiment, a length of the sectionwhere the pattern is disposed may be about ninety percent (90%) or moreof the length of the siderail 42, 44. In another exemplary embodiment, alength of the section where the pattern is disposed may be aboutninety-five percent (95%) or more of the length of the siderail 42, 44.After reviewing this disclosure, one skill in the art will appreciatethe size of the pattern may be larger or smaller, such as larger orsmaller than the length of the siderails 42, 44.

The sides 108, 110 of the supports 100 may be at least partially boundedby a joint 114, and the joint 114 may be formed by at least a portion ofthe inner wall 54 and the outer wall 56 of the lip 30 in contact orclose proximity. For example, a portion of the inner wall 54 and theouter wall 56 may contact or touch to form the joint 114.

As shown in the accompanying figures, a joint 114 may be disposed oneach side of the support 100, such as the first side 108 and the secondside 110. The joints 114 may at least partially separate adjacentsupports 100. The joints 114 may also at least partially or entirelyprevent direct fluid communication between adjacent supports 100 whenthe joint is disposed between adjacent supports 100.

The joints 114 may provide additional support for the lip 30. Forexample, if the joint 114 contacts or is disposed at least proximate theouter wall 56, the joint 114 may provide additional reinforcement and/orstrengthening of the outer wall 56 of the lip 30. This additionalreinforcement and/or strengthening may help prevent the lip 30 frominadvertently bending or deforming when a force is applied.

The joint 114 may have a height measured between a proximal end, whichmay be disposed at least proximate the lower portion 16 of the tabletop12, and a distal end, which may be disposed towards the distal portion52 of the lip 30. The joints 114 may be disposed in a pattern, and thepattern may include a plurality of joints. For example, the pattern mayinclude one or more joints 114 and the joints 114 may be disposed in agenerally consistent arraignment. In addition, the joints 114 in thepattern may have a generally constant height, and the joints 114 may bespaced apart by a generally constant distance. The joints 114 disposedin the pattern may have generally the same size, shape, configuration,and arrangement, and the joints 114 may be disposed in a generallyuniform arrangement, which may help create a tabletop 12 with generallyuniform properties and characteristics.

The pattern may also include the supports 100 and the joints114 disposed in a generally consistent arrangement. For instance, thesupports 100 and the joints 114 in the pattern may be spaced apart by agenerally constant distance. In an exemplary embodiment shown in FIGS.4A-4C, the supports 100 and the joints 114 may be disposed in agenerally parallel configuration, and at least a portion of the patternmay include alternating supports 100 and joints 114. In addition, theproximal ends of the supports 100 and the joints 114 may be generallyaligned along an axis or in a straight line, and the distal ends of thesupports 100 and the joints 114 may be generally aligned along an axisor in a straight line. As shown in the accompanying figures, theproximal and distal ends of the supports 100 and the joints 114 may bedisposed along generally parallel axes.

The joints 114 may have a double wall thickness that is generally equalto a thickness of the inner wall 54 and the outer wall 56 of the lip 30.The joint 114 may have generally the same thickness as the distal end 52of the lip 30 because the distal end 52 of the lip 30 may include acompression edge. Thus, in an exemplary embodiment, the joint 114 andthe distal end 52 of the lip 30 may have generally the same thickness.

In an exemplary embodiment, the supports 100 and the joints 114 may bedisposed along one or more sides 20, 22 and/or ends 24, 26 of thetabletop 12. For example, the supports 100 and the joints 114 may bedisposed along the portions of the tabletop 12 sized and configured tobe connected to the frame 40. The supports 100 and the joints 114 mayfacilitate connection of the siderails 42, 44 to the tabletop 12, and agenerally uniform pattern of the supports 100 and the joints 114 maycreate a tabletop 12 with generally uniform properties andcharacteristics.

The inner wall 54 of the lip 30 may also include other structures orfeatures, such as one or more attachment portions 116. The attachmentportions 116 may be sized and configured to facilitate attachment of theframe 40 to the tabletop 12. In particular, the attachment portions 116may facilitate attachment of the siderails 42, 44 of the frame 40 to thetabletop 12. The attachment portions 116 may be disposed in the innerwall 54 of the lip 30, and the attachment portions 116 may protrudeinwardly towards the center portion 34 of the tabletop 12. Theattachment portions 116 may include an upper or proximal portion 118that may be connected to the lower portion 16 of the tabletop 12.

One or more of the attachment portions 116 may be disposed in a pattern,and the attachment portions 116 disposed in the pattern may have agenerally consistent size, shape, configuration, and/or arrangement. Thepattern may include other structures such as one or more of the supports100 and/or the joints 114. For example, the attachment portions 116 maybe generally aligned with the supports 100 and/or the joints 114 alongthe inner wall 54 of the lip 30. In addition, the lower portion 120 ofthe attachment portions 116 may be generally aligned with and/ordisposed in a generally parallel configuration with the lower portion104 of the supports 100. The contact surface 122 of the attachmentportion 116 may also be generally aligned with and/or disposed in agenerally parallel configuration with the contact surface 106 of thesupport 100. Thus, the pattern may include one or more of the supports100, the joints 114, and the attachment portions 116, and thesestructures may be generally aligned.

The sides 124, 126 of the attachment portions 116 may be at leastpartially bounded by one or more joints 114. For example, a first joint114 may be disposed on the first side 124 of the attachment portions 116and a second joint 114 may be disposed on the second side 126 of theattachment portions 116. The joints 114 may at least partially separatethe attachment portions 116 from other structures, such as adjacentsupports 100. The joints 114 may also at least partially or entirelyprevent direct fluid communication between the attachment portion 116and adjacent structures, such as adjacent supports 100.

The attachment portions 116 may have a generally constant height. Theheight of the attachment portions 116 may be generally equal to theheight of the supports 100 and/or the joints 114. If the supports 100,the joints 114, and/or the attachment portions 116 have generally thesame height, the supports 100, the joints 114, and the attachmentportions 116 may be generally in a row and/or a straight line.

The attachment portions 116 may be disposed in a pattern, and thepattern may include one or more of the supports 100 and/or the joints114. For example, the pattern may include the supports 100, the joints114, and/or the attachment portions 116 disposed in a generallyconsistent arraignment.

The proximal portion 50 of the lip 30 may include the supports 100, thejoints 114, and the attachment portions 116. The distal portion 52 ofthe lip 30 may include the inner wall 54 and the outer wall 56 in closeproximity. When the inner and outer walls 54 and 56 of the lip 30 are bedisposed in close proximity, the walls 54, 56 may be spaced apart byabout 5 mm (0.2 in.) or less, such as about 4 mm (0.16 in.), about 3 mm(0.12 in.), about 2 mm (0.08 in.); about 1 mm (0.04 in.), about 0.5 mm(0.02 in.), or less. At least a portion of the inner and outer walls 54,56 may touch or contact, which may form a compression edge 130. Forexample, the inner wall 54 and the outer wall 56 may be disposed in agenerally parallel configuration, and at least a portion of an innersurface of the inner wall 54 and at least a portion of an inner surfaceof the outer wall 56 may contact or touch to form the compression edge130.

The compression edge 130 may have a generally consistent size, such as aheight. For example, the compression edge 130 may have an average heightgenerally equal to about fifty percent (50%) of a height of the lip 30.The compression edge 130, however, may be larger or smaller. Forexample, the compression edge 130 may be greater than about fiftypercent (50%) of the height of the lip 30, such as about sixty percent(60%), about seventy percent (70%), about eighty percent (80%), aboutninety percent (90%), or more. The compression edge 130 may also have aheight less than about fifty (50%) of the height of the lip 30, such asabout forty percent (40%), about thirty percent (30%), about twentypercent (20%), about ten percent (10%), or less.

In an exemplary embodiment, the compression edge 130 may have an averageheight that is equal to about twenty-five percent (25%) of the height ofthe inner wall 54 of the lip 30. The supports 100, the joints 114,and/or the attachment portions 116 may have an average height this isequal to about seventy-five percent (75%) of the height of the innerwall 54 of the lip 30. Thus, the ends of the supports 100, the joints114, and/or the attachment portions 116 may meet and/or may be connectedto the compression edge 130. After reviewing this disclosure, one skillin the art will appreciate that the supports 100, the joints 114, theattachment portions 116, and the compression edge 130 may be larger orsmaller. For example, the compression edge 130 could be greater thanabout twenty-five percent (25%) of the height of the inner wall 54 ofthe lip 30, such as about thirty present (30%), about thirty-fivepercent (35%), about forty percent (40%), about forty-five percent(45%), about fifty percent (50%), about fifty-five percent (55%), aboutsixty percent (60%), about sixty-five percent (65%), about seventypercent (70%), or more. The compression edge 130 could also be smaller,such as an average height that is less about twenty-five percent (25%)of the height of the inner wall 54 of the lip 30, such as about twentypresent (20%), about fifteen percent (15%), about ten percent (10%),about five percent (5%), or less. The corresponding height of thesupports 100, the joints 114, the attachment portions 116 may be largeror smaller.

The compression edge 130 may have a generally uniform size, and thecompression edge 130 may extend about all or at least a portion of theperimeter 32 of the tabletop 12. For example, the compression edge 130may extend about at least a portion of the sides 20, 22, the ends 24,26, the corners 28, and/or the perimeter 32 of the tabletop 12. Thecompression edge 130 may have a generally uniform area of contactbetween the inner wall 54 and the outer wall 56 of the lip 30. Thecompression edge 130 may form at least a portion, substantially all, orthe entire distal portion 52 of the lip 30. The compression edge 130 mayprovide additional rigidity and/or strength to the distal portion 52 ofthe lip 30. The compression edge 130 may have generally the same height,and the compression edge 130 may form the distal portion 52 of the lip30. Advantageously, if the compression edge 130 has a generally uniformsize, shape, configuration, and/or arrangement, the distal portion 52 ofthe lip 30 may have generally uniform properties and characteristics.

In an exemplary embodiment, the distal portion 52 of the lip 30 mayinclude the compression edge 130 and the proximal portion 50 of the lip30 may include the supports 100, the joints 114, and/or the attachmentportions 116. The lower portion of the supports 100, the joints 114,and/or the attachment portions 116 may be disposed at least proximate anupper portion of the compression edge 130. If desired, the lower portionof the supports 100, the joints 114, and/or the attachment portions 116may contact or touch the compression edge 130. If each of the supports100, the joints 114, the attachment portions 116, and the compressionedge 130 have generally the same size, shape, configuration, and/orarrangement, the lip 30 may have generally uniform properties andcharacteristics.

The table 10 may include other features, components, and structures,such a receiving portion 132. The receiving portion 132 may be sized andconfigured to receive a portion of an adjacent table when the tables aredisposed in a nested configuration. For example, the receiving portion132 may be at least partially formed in the upper portion 14 and theouter wall 56 of the lip 30, and the receiving portion 132 may includean inner surface 134. The inner surface 134 of the receiving portion 132may be disposed at least proximate an upper portion of the supports 100,the joints 114, and/or the attachment portions 116. If desired, aportion of one or more of the supports 100, a portion of one or more ofthe joints, and/or a portion of one or more of the attachment portions116 may contact or support the receiving portion 132. The receivingportion 132 may be similar to one or more of the receiving portionsdescribed in U.S. Pat. Nos. 8,347,795; 8,397,652; 8,408,146; 8,578,863;8,622,007; and 9,138,050; each of which incorporated by reference in itsentirety. In addition, the table 10 and tabletop 12 may include one ormore features, aspects, or components, such as shown in U.S. Pat. Nos.8,347,795; 8,397,652; 8,408,146; 8,578,863; 8,622,007; and 9,138,050;each of which incorporated by reference in its entirety.

The supports 100, the joints 114, the attachment portions 116, and/orthe compression edge 130 may provide increased structural integrityand/or rigidity. For example, the supports 100, the joints 114, theattachment portions 116, and/or the compression edge 130 may provideincreased structural integrity and/or rigidity to the lip 30, which mayhelp prevent unintentional bending, bowing, or flexing of the lip 30.The supports 100, the joints 114, the attachment portions 116, and/orthe compression edge 130 may also provide increased structural integrityand/or rigidity to the receiving portion 132. The increased structuralintegrity and/or rigidity of the receiving portion 132 may facilitatenesting of the tables because the receiving portion 132 may be able tosupport a larger amount of force or weight. For instance, in the stackedconfiguration, the distal end 52 of the lip 30 of an upper table may bedisposed in the receiving portion 132 of a lower table. Accordingly, astress associated with the stacked tables may be applied to thereceiving portion 132, and a table at or near the bottom of a pluralityof stacked tables may be under significant force from the weight of thestacked tables. Because the receiving portion 132 may be supported byone or more of the supports 100, one or more of the joints 114, and/orone or more of the attachment portions 116, the reinforced receivingportion 132 may enable additional tables to be disposed in the stackedconfiguration and/or reduce the likelihood that the tables are damagedin the stacked configuration.

The table 10 may include other features, components, and structures,such an alignment portion 140. The alignment portion 140 may be sizedand configured to facilitate attachment, alignment, and/or positioningof a cross member, crossbar, or the like. For example, the alignmentportion 140 may be used in connection with the cross member 62. Thealignment portion 140 may also be used in connection with other suitablestructures and components.

The alignment portion 140 may be disposed in the inner wall 54 of thelip 30, and the alignment portion 140 may protrude inwardly towards thecenter portion 34 of the tabletop 12. The alignment portion 140 mayinclude an upper portion 142 connected to the lower portion 16 of thetabletop 12. The alignment portion 140 may include a lower portion 144which may be disposed towards the distal portion 52 of the lip 30. Thealignment portion 140 may include a contact surface 146, and the contactsurface 146 may be sized and configured to contact a portion of theframe 40, such as the first segment 72 of the siderail 42, 44. The lowerportion 144 of the alignment portion 140 may be sized and configured tobe disposed at least proximate the second segment 74 of the siderail 42,44. The alignment portion 140 may include a first side 148 and a secondside 1150, and the alignment portion 140 may include one or more roundedsurfaces or corners, such as rounded corners. The alignment portion 140may include a volume or hollow interior portion 152, and the hollowinterior portion 152 may be in fluid communication with the hollowinterior portion 18 of the tabletop 12.

The alignment portions 140 may be disposed in pairs and may be generallyaligned with the cross member 62. For example, the cross member 62 mayextend through the openings 68, 78 in the siderail 42, 44 and the endsof the cross member 62 may be disposed at least proximate the contactsurface 146 of the alignment portions 140. The alignment portion 140 mayinclude one or more guides 154, and the guides 154 may facilitatepositioning of the cross member 62. For example, the guides 154 mayextend inwardly towards the center portion 34 of the tabletop 12 and theguides 154 may facilitate positioning of the cross member 62. The guides154 may be sized and configured to help prevent unintended movement ofthe cross member 62, and the guides 154 may help maintain the crossmember 62 in the desired position.

The alignment portions 140 may be disposed along the inner surface 54 ofthe lip 30, and each of the alignment portions 140 may have generallythe same size, shape, configuration, and/or arrangement. The alignmentportions 140 may be disposed in the proximal portion 50 of the lip 30,and the alignment portions 140 may be disposed at least proximate theintersection of the lip 30 and the tabletop 12. The alignment portions140 may be sized and configured to be enclosed or at least partiallybounded by the lip 30 and the siderails 42, 44.

The alignment portions 140 may be part of a pattern, such as one or moreof the exemplary patterns disclosed herein. The pattern may include oneor more of the supports 100, the joints 114, the attachment portions116, and/or the alignment portions 140. The alignment portions 140 maybe generally aligned with the supports 100, the joints 114, and/or theattachment portion 116 as part of the pattern. In an exemplaryembodiment of the pattern, the supports 100, the joints 114, theattachment portions 116, and/or the alignment portions 140 may havegenerally the same height, spaced apart by generally constant distances,generally aligned along an axes, disposed in generally parallelconfiguration, disposed in a generally consistent or regular pattern,and/or disposed in a generally straight line in the inner wall 54 of thelip 30. One or more of the supports 100, the joints 114, the attachmentportions 116, and/or the alignment portions 140 may have generallyconsistent sizes, shapes, configurations, and arrangements. This mayallow the proximal ends of the supports 100, the joints 110, theattachment portions 116, and/or the alignment portions 140 to be alignedalong an axis or in a straight line, and the distal ends of the supports100, the joints 110, the attachment portions 116, and the alignmentportions 140 to be generally aligned along an axis or in a straightline. Additionally, the proximal and distal ends of the supports 100,the joints 110, the attachment portions 116, and/or the alignmentportions 140 may be disposed along generally parallel axes.

The height of the alignment portion 140 may be generally equal to theheight of the supports 100, the joints 114, and/or the attachmentportions 116. The generally equal height may allow one or more of thesupports 100, the joints 114, the attachment portions 116, and/or thealignment portions 140 to be disposed in a row or generally straightline.

The sides 148, 150 of the alignment portion 140 may be at leastpartially bounded by one or more joints 114. For example, a first joint114 may be disposed on the first side 148 of the alignment portion 140and a second joint 114 may be disposed on the second side 150 of thealignment portion 140. The joints 114 may at least partially separatethe alignment portion 140 from other structures, such as adjacentsupports 100. The joints 114 may also at least partially or entirelyprevent direct fluid communication between the alignment portion 140 andadjacent structures, such as adjacent supports 100.

As discussed above, the lip 30 may form an outer boundary or be disposedabout at least a portion of the perimeter 32 of the tabletop 12. If thetabletop 12 is constructed from blow-molded plastic, the lip 30 may bedifficult to form during the blow-molding process because the gas mayhave to flow to the outermost portions of the structure. In addition,the gas must have sufficient pressure to form the lip 30. Thus, the lip30 may be difficult to form during the blow-molding process because thegas may have to travel significant distances and/or reach remoteportions of the structure, and the gas has to be at the correct pressureto properly form the lip 30. If the gas flow and/or pressure areincorrect, then the lip 30 may not be properly formed during theblow-molding process and that may result in failure. It was previouslyknown in the art to have gas flow passages that extend to the lower endof the lip to allow sufficient gas flow at the desired pressure to formthe lip. It was previously thought that gas flow passages needed toextend to the lower end of the lip to allow the lip to be fully andcompletely formed during the blow-molding process. A surprising andunexpected result is the supports 100, the joints 114, the attachmentportions 116, and/or the alignment portions 140 may not extend to thelower end of the lip 30, and the compression edge 130 may form thedistal portion 52 of the lip 30 without any gas flow passages thatextend to the lower end of the lip. Thus, the lip 30 of the tabletop 12may be fully and completely formed during the blow-molding processwithout the gas flow passages that were previously required. One skilledin the art at the time of the invention did not expect or anticipatethat a tabletop could be formed from blow-molded plastic in which thedistal portion of the lip is a compression edge without any gas passagesextending into the lower end of the lip, and the proximal portion of thelip may include a plurality of the supports, the joints, the attachmentportions, and/or the alignment portions. In contrast, one skilled in theart at the time of the invention would have expected the lip to not beproperty formed during the blow-molding process. One skilled in the artat the time of the invention would have expected the lip to not properlyform and the tabletop to be a failure because, among other reasons,there would not be sufficient gas flow and pressure to allow the lip tobe formed during the blow-molding process. The supports 100, the joints114, the attachment portions 116, and/or the alignment portions 140disposed in the proximal portion 50 of the lip 30, however, allow thecompression edge 130 to form the distal portion 52 of the lip 30.

After reviewing this disclosure, one skilled in the art will appreciatethat the table 10, the tabletop 12, and accompanying features, aspects,and components, may have different shapes, sizes, configurations and/orarrangements depending, for example, upon the intended use of the table10. It will also be understood that the table 10 and tabletop 12 and mayinclude any suitable number and combination of features, aspects, andcomponents; but none of the features, aspects, or components may berequired. In addition, one skilled in the art, after reviewing thisdisclosure, will be understood that table 10 and the tabletop 12 mayhave other features, aspects, and components.

In another exemplary embodiment, such as shown in FIGS. 9-15 , thetabletop 12 may not include one or more of the features, aspects, orcomponents described above and/or the tabletop 12 may include one ormore additional features, aspects, and/or components. For example, thetabletop 12 may have generally the same size, shape, configuration, andarrangement as the exemplary tabletop 12 described above (forconvenience and readability, the same reference numbers may be used forsimilar or related features and components), but the tabletop 12 may notinclude the supports 100 and/or the joints 114. The tabletop 12 mayinclude the attachment portions 116 sized and configured to attach theframe 40 to the tabletop 12. As shown in the accompanying figures theinner wall 54 of the lip 30 may be a generally planar structure otherthan the periodic spacing of the attachment portions 116.

As shown in FIG. 9 , the inner surface 54 of the lip 30 may include oneor more guides 202. The guides 202 may be disposed in the inner surface54 of the lip 30, and a pair of guides 202 may disposed proximate wherethe cross member 62 is connected to the frame 40. In an exemplaryembodiment, a pair of guides 202 may be disposed proximate each end ofthe siderails 42, 44, and the guides 202 may be generally aligned withthe cross member 62. For example, the cross member 62 may extend throughthe openings 68, 78 in the siderails 42, 44 and the ends of the crossmember 62 may be disposed at least proximate the guides 202. The guides202 may facilitate positioning of the cross member 62. For example, theguides 202 may extend inwardly towards the center portion 34 of thetabletop 12, and the guides 202 may be aligned with one or more portionsof the cross member 62. The guides 202 may be sized and configured tohelp prevent unintended movement of the cross member 62, and the guides202 may help maintain the cross member 62 in the desired position.

The tabletop 12 may include one or more stops 204 and the stops 204 maybe sized and configured to facilitate positioning of the siderails 42,44 of the frame 40. For example, the stops 204 may be disposed towardsthe ends 24, 26 and/or corners 28 of the tabletop 12, and the siderails42, 44 may be disposed between the stops 24. The ends of the siderails42, 44 may contact the stops 204 and the stops may guide placement ofthe siderails 42, 44 during the manufacturing and/or assembly process.The stops 204 may also help prevent undesired twisting or bending of thetabletop 12. For instance, the stops 204 may help prevent the siderails42, 44 from undesirably moving during use of the table 10. Further, theengagement of the siderails 42, 44 with the stop 204 may help maintainthe siderails 42, 44 in a desired position, and the stops 204 may helpabsorb forces or impacts applied to the table top 200.

The tabletop 12 may include an elongated tack-off 206, and the elongatedtack-off may be disposed between the attachment portions 116, betweenthe attachment portions 116 and the stops 204, and the like. Theelongated tack-off 206 may be formed by an outer wall 56 and an innerwall 54 of the lip 30 being in close proximity or contact. For example,the outer wall 56 and the inner wall 54 may at least partially touch orbe in substantial proximity. A portion of the outer wall 56 and theinner wall 54 may also touch, connect, interlock, mesh, join, orotherwise be in contact.

The elongated tack-off 206 may be disposed at least proximate theintersection of the lip 30 and the tabletop 12. The elongated tack-off206 may form a joint or coupling between the lip 30 and the centerportion 34 of the tabletop 12. The elongated tack-off 206 may also forma solid structure between the lip 30 and the center portion 34 of thetabletop 12, and the solid structure may help securely connect the lip30 and the tabletop 12. The solid structure may have increased strength,structural integrity, and/or rigidity because it may have a double wallthickness. The solid structure may also prevent fluid communicationbetween the lip 30 and the center portion 34 of the tabletop 12.

As shown in FIGS. 9-15 , the exemplary frame 40 may have a differentsize, shape, configuration, and/or arrangement than the frame describedin connection with FIGS. 1-8 . For example, the second segment 74 of thesiderail 42, 44 may be disposed generally perpendicular to the firstsegment 72 and/or the third segment 76 of the siderail 42, 44. Thesecond segment 74 may be disposed generally parallel to the uppersurface 80 and/or the lower surface 82 of the siderail 42, 44. Thesecond segment 74 may also be disposed generally perpendicular to theinner surface 66 and/or the outer surface 70 of the siderail 42, 44.After reviewing this disclosure, one skilled in the art will appreciatethat the frame may have other suitable shapes, sizes, configurations,and/or arrangements.

The lip 30 may also have other suitable shapes, sizes, configurations,and/or arrangements, such as shown in the exemplary embodiments shown inFIG. 9-15 . For example, the proximal portion 50 of the lip 30 mayinclude the attachment portions 116, and the attachment portions 116 maybe formed in the inner wall 54 of the lip 30. The attachment portions116, however, may not be disposed proximate or adjacent to one or moreof the joints 114. In an exemplary embodiment shown in FIGS. 9-15 , thelip 30 may not include the joints 114.

The proximal portion 50 the lip 30 shown in connection with theexemplary tabletop 12 may include the inner wall 54 and the outer wall56 of the lip 30 spaced apart by a distance. For example, the inner wall54 and the outer wall 56 may be spaced apart by a first distance, suchas where the attachment portion 116 is disposed (exemplary embodimentsof which are shown in FIGS. 10 and 14 ). The proximal portion 50 mayinclude the inner and outer walls 54, 56 of the lip 30 spaced apart by adistance, such as where the elongated tack-off 206 is disposed(exemplary embodiments of which are shown in FIGS. 11, 13, and 15 ).

The distal portion 52 of the lip 30 may include the inner and outerwalls 54, 56 separated by a distance. The distance separating the innerand outer walls 54, 56 in the distal portion 52 of the lip 30 may begenerally equal to the distance separating the inner and outer walls 54,56 where the elongated tack-off 206 is disposed. One skilled in the art,after reviewing this disclosure, will appreciate that the lip 30 mayhave other suitable shapes, sizes, configurations, and/or arrangements.

The guides 202 and the alignment portions 140 may have a similar purposeor function, but different structures. For example, the alignmentportions 140 may be formed in the inner wall 54 of the lip 30, and thealignment portions 140 may extend inwardly towards the center portion 34of the tabletop 12. The guides 202, however, may be formed in the innerwall 54 of the lip 30, and the guides 202 may protrude or projectinwardly towards the center portion 34 of the tabletop 12. Thus, in anexemplary embodiment, the inner wall 54 of the lip 30 may be a generallyplanar structure, but may include one or more inwardly extendingstructures such as the attachment portions 116 and/or the guides 202.

After reviewing this disclosure, one skilled in the art will understandthat the table 10, and parts and components of the table 10 such as thetabletop 12, may have different shapes, sizes, configurations and/orarrangements depending, for example, upon the intended use of the table10. It will also be understood that the table 10 and tabletop 12 and mayinclude any suitable number and combination of features, aspects, andcomponents; but none of the features, aspects or components may berequired. In addition, it will be understood that features, aspects, andcomponents may have particular shapes, sizes, configurations, and/orarrangements depending, for example, upon projected use, intendedfunction, and/or desired strength, rigidity, and/or structuralintegrity.
